Do you really need an ERP?

ERP systems are powerful, but they are not automatically the right answer for every organisation.

ERP systems are powerful, but they are not automatically the right
answer for every organisation.

The acronym itself can make a software project sound more necessary than
it actually is.

Before buying or building an ERP, start with the problems you need to
solve.

What does an ERP do?

An ERP generally connects multiple organisational functions through a
common system.

Depending on the product, this may include:

  • Finance.
  • Procurement.
  • Inventory.
  • Sales.
  • Human resources.
  • Projects.
  • Operations.
  • Reporting.

The main value is integration.

When an ERP makes sense

An ERP may be appropriate when:

  • Multiple departments depend on shared data.
  • Processes are complex and interconnected.
  • The organisation has significant transaction volume.
  • Standardised controls are required.
  • Management needs integrated reporting.
  • Existing systems create substantial duplication.

When you probably do not need one

An ERP may be unnecessary if your organisation simply needs:

  • A better expense tracker.
  • Appointment management.
  • A simple CRM.
  • Inventory tracking.
  • Automated reporting.
  • A document workflow.
  • A small internal application.

Buying a large ERP to solve a small problem can create unnecessary cost
and complexity.

Consider the process first

Suppose an organisation says:

"We need an ERP because procurement is difficult."

The real requirement might be:

Request → Approval → Purchase → Delivery → Invoice → Payment

That workflow could potentially be improved without implementing an
entire ERP.

The cost of complexity

ERP projects can require:

  • Data migration.
  • Process redesign.
  • User training.
  • Configuration.
  • Integrations.
  • Change management.
  • Ongoing administration.

The software licence is only one part of the total cost.

Start smaller where possible

A practical approach is to identify the highest-value problem first.

Improve that workflow.

Measure the result.

Then determine whether other processes should be connected.

The bottom line

An ERP is a business strategy decision, not simply an IT purchase.

If your organisation needs integrated enterprise-wide processes, an ERP
may be appropriate.

If you only need to solve one or two operational problems, a smaller
solution may be better.
